Sometimes the animation looks weird and not realistic.

For example when a soldier turns around its own axis.

I propose to make a movable body of the soldier, as the inclusion of options "Aiming Deadzone", but when moving body "Rifle Scope" of the weapon should also remain in the center of the screen.

I suggest that a moving body of the soldier on independently of the "Aiming Deadzone" and When you disable, tethering the camera to a rifle, not to the feet.

At the turn of the animation is realistic, first turn the body, followed by the legs.

This is realized in the animation "Battlefield 3"
